通过单因素实验研究了常压、恒温水浴条件下提钒尾渣脱碱规律，确定了脱碱提钒尾渣配矿烧结工艺参数及路线. 结果表明，碱性体系中引入CaO，提钒尾渣中的方钠石、钙霞石等铝硅酸钠相不再是稳定固相，Ca2+会替换2个Na+生成更稳定的钙石榴石相，使钠离子进入溶液溶出. 在NaOH添加量为提钒尾渣质量的20%及CaO过量系数为2的条件下，提钒尾渣中的Na2O含量减少至0.9%；脱碱后尾渣替代低钒高品位铁精矿粉用于配矿炼铁，配加量约为20 kg/t，配加前后对烧结工艺参数没有影响，且由于承钢钒钛矿SiO2品位低，配加尾渣后成品烧结矿指标明显改善，其机烧矿转鼓指数提高0.6%.

The rule of removing alkali from the extracted vanadium residue was investigated under atmospheric pressure and constant temperature water bath through single factor experiment, and the parameters and the route of the ore blending and sintering process of the extracted vanadium residue after removal of alkali were determined. The experimental results showed that adding CaO in alkaline system, sodalited and cancrinite in the extracted vanadium residue is no longer stable solid phase, two Na+ was replaced by Ca2+ to produce a more insoluble calcium garnet phase, so that Na+ dissolved into the solution. Under the additive amount of NaOH was 20% of the extracted vanadium residue and the excess coefficient of CaO was 2, the content of Na2O in the extracted vanadium residue was decreased to 0.9%. Using the extracted vanadium residue after removal of alkali replaced of low vanadium high grade iron concentrate powder for ore blending and iron making, the added amount was about 20 kg/t, and the amount had no influence on the sintering parameters. And the sinter indexes of finished product were improved obviously after adding residue thanking for the low grade of SiO2 in the vanadium-titanium ore of Chengsteel Group Co., Ltd., and the drum index also improved by 0.6%.
